Seeds can be sown directly in the garden in winter or early spring / or sown in punnets indoors at any time for earlier plants.
Caution: Wear gloves when handling the seed, and when handling any part of the plant.
Though there is little risk from the seed, but it is wise to treat all parts of any Aconitum with respect.
All parts of the plant are toxic if ingested.

Indoors for early plants: First sow the seed in a punnet on surface of good quality seed raising mix.
Now cover to 5cm depth with sieved seed mix or vermiculite.

Then thoroughly moisten by standing the punnet in a shallow water bath.
And allow the water to percolate up to the surface of the mix from the bottom.
This will ensure the mix is thoroughly moist but not drenched.

Label the punnet with the name and date sown.

For best germination

First keep moist in a well lit position at a temperature of approx. 25C for 14 days.
And the punnet can be kept moist by misting from a spray water bottle.
Covering the punnet with a clear plastic cover, plastic bag, or glass will help retain consistent moisture and prevent drying out.

Give a period of chilling

Now the seeds need a period of chilling (a pretend winter) – so wrap the sown, moist punnet in cling-wrap and place in fridge (not freezer) for 21 days.

Then take out, unwrap punnet, and keep moist in approx. 25C, in a well lit position.

Seeds need good light to sprout, but the punnet should not be in direct sunlight.
Seeds germinate in approx. 30 days.

Or sow seeds directly in garden in autumn/winter and leave to get the required chilling from nature to occur over winter before germinating in the spring.

Seed Count: 10 seeds per packet approx.
(We aim to exceed the stated count, and give a generous serve)
